Are there any visual elements commonly associated with AI?
A characteristic visual element for neural network might be the node diagram, which shows (schematically) the nodes in the layers of a neural network and the connections between the nodes, both within and between the layers, that get weighted as the network is trained.

If you do a Google search on "neural network node diagram", you will see what I mean.

You might also think of any sort of video or photo with computer-identified features highlighted, as in a Google image search for "machine vision feature detection".

If you are looking for something more concrete, you can think of racks of GPU cards, or a spinning LIDAR scanner.
